The humid summers in Frederick, Maryland, can get muggy and uncomfortable. You adjust the thermostat to a ideal temperature. The air conditioning begins running right away. But, even after your AC operates, your home still feels damp and sticky.
That’s not very comfortable.
It can be annoying when the air conditioner seems to operate normally, yet your home doesn't actually feel very comfortable. If your rooms feel humid but thermostat says cool, you're not alone. Local homeowners often have this experience.
The reason is simple: Temperature and humidity are two different things. Your temperature only tells you how warm or cool the air is within the space. It doesn't measure the amount of moisture in the air. When moisture levels are too high, your home can feel much hotter than the thermostat indicates, due to indoor humidity problems.
In this article, you'll learn how humidity affects your home comfort, common reasons your home feels humid even when the temperature is correct and easy troubleshooting steps you can try to reduce humidity in your Frederick, Maryland, home. That way, you’ll know when to contact experts like the team at May's Heating & Air for expert assistance.
Why Your Home Can Feel Humid Even Though the Temperature Is Cool
The temperature is only part of what makes your house enjoyable. Indoor humidity is another important factor. The majority of homes are the most comfortable when indoor relative humidity stays 30-50 percent. When a home has high indoor humidity, the air feels warmer, heavier and stickier—even if the actual air temperature is cool.
Too much indoor moisture can also promote dangerous mold growth, mildew, unpleasant odors and other indoor air quality issues. That's why your house feels humid but the AC is running—your system may be cooling the air without extracting enough moisture.
8 Common Reasons Your Home Feels Humid
Residing in Frederick, Maryland, excess moisture can be a frequent concern.
Plenty of area homeowners ask the same question: What's making my house feel humid?
There are a variety of common explanations. Identifying what's creating excess humidity is a key first step toward fixing the problem.
Here are several common reasons for high indoor humidity levels in Frederick, Maryland:
1. Oversized Air Conditioner
An AC that's too big for your home cools your home too quickly. The problem is an oversized AC often doesn’t remove humidity effectively because it stops operating before completing a complete cooling cycle.
2. Clogged Air Filter
A clogged air filter reduces airflow throughout your HVAC system. This makes it more difficult for your equipment to control humidity while cooling your home.
3. Obstructed Condensate Drain
Your air conditioning removes moisture from your home’s air and and then it drains from the equipment through a condensate line. If that drain becomes clogged, moisture can't exit the system properly, contributing to increased humidity levels.
4. Frozen Evaporator Coil
The evaporator coil pulls both heat and moisture from your home's air. Dirt and grime on the coil reduces its effectiveness and often requires professional AC repair services to restore performance.
5. Damaged Ductwork
Ductwork carries cool air throughout your home. Leaks in ductwork can draw warm, humid air from attics, crawl spaces or other unconditioned areas into your HVAC system. This additional moisture makes it more challenging to maintain comfortable humidity conditions.
6. Thermostat Fan Running on “On” Change to “Auto”
If your thermostat fan is set to "On" instead of "Auto", the blower continues running after the cooling cycle ends. This can blow moisture collected on the evaporator coil back into your home instead of letting it to drain away.
7. Extremely Humid Weather
During the area’s very humid summers, your HVAC system has to operate more to remove moisture from the air. Even when your air conditioning is functioning as designed, sometimes your home feels muggy because outdoor humidity continually enters your home through doors, windows and normal air leakage.
8. Poorly Maintained Heating and Cooling Equipment
As HVAC systems age, they often become less capable at controlling humidity. HVAC maintenance improves performance, boosts efficiency and helps identify worn-out parts. Neglecting regular air conditioning maintenance can reduce performance, including your system's ability to reduce moisture.
What You Can Check Before Scheduling an HVAC Technician
If your home feels humid, there are a few simple things you can check before scheduling service. These DIY tips are easy ways to improve indoor comfort by helping your AC or heating system remove moisture more effectively.
- Replace a dirty air filter. A clean HVAC air filter allows proper airflow, helping your system cool and dehumidify your home more efficiently.
- Verify the thermostat fan is set to Auto. This allows moisture to leave the system after each cooling cycle instead of being sent back into your living spaces.
- Make sure supply and return vents are open and not covered up. Rugs or furniture over the vents or closed vents can restrict airflow throughout your home.
- Check for water around the indoor unit. Water near your AC equipment may suggest a clogged condensate drain or another drainage issue.
- Pay attention to how your air conditioning should run. If the AC is short cycling or turning on and off continuously, or it seems to run constantly without cooling your home like it should, it's time to have the system inspected by a professional.
Even if your thermostat still says cool but house feels humid, do not perform repairs with refrigerant, electrical components or system components. DIY repairs may be tempting, but these repairs require advanced training and should always be handled by a qualified HVAC technician.
Could You Benefit from a Whole-Home Dehumidifier?
If you struggle with humidity in your house during summer or year-round moisture problems, a whole-home dehumidifier may be worth considering.
